132. Preparation and Characterization of High-Melt-Strength Polylactide with Long-Chain Branched Structure through γ-Radiation-Induced Chemical Reactions
摘要：采用一种制备高熔体强度聚乳酸材料简易方法，通过对混合了一种三官能基团单体，三羟甲氧基丙烷三丙烯酸酯（TMPTA）的线性聚乳酸进行伽马射线辐照，引发自由基反应，在体系中引入长链支化结构。配备多角度激光光散射检测仪的体积排除色谱测试结果表明所制备的长链支化聚乳酸的分子量和长链支化度随着加入TMPTA用量增加而提高。黏度，储能模量，损耗角，Cole-Cole作图，和松弛时间谱等流变学特性说明长链支化聚乳酸的熔体强度...

High-efficiency loading in small mesopores (2–3 nm) forming a matrix type controlled drug delivery nanosystem
Herein a high-efficiency controlled release nanosystem for fluoroquinolonehydrochlorides was established by a characteristicvacuum-recrystal loaded process based on small pore mesoporousMCM-41. The system exhibited great drug loading capacity (62.31%),matrix type sustained-release behavior (5 days) and excellent biocompatibility in vitro.

Rattle-type microspheres as support of tiny sized gold nanoparticles for high efficient catalysis efficient catalysis
SiO2/poly(ethyleneglycol dimethacrylate) (PEGDMA) rattletype microspheres loaded with tiny sized gold nanoparticles (B2 nm) were prepared through a facile and novel method. Catalyzed reduction of 4-nitrophenol with NaBH4 demonstrated that this rattle-type microsphere possessed high catalytic efficiency.

Investigation on the role of the molecular weight of polyvinyl pyrrolidone in the shape control of high-yield silver nanospheres and nanowires
Serving as shape control agent, polyvinyl pyrrolidone (PVP) has been widely used in chemical synthesis of metal nanoparticles. However, the role of molecular weight (MW) of PVP has been rarely concerned. In this study, we show a facile method to control the shapes of silver nanocrystals using PVP with different MWs. PVPMW=8,000, PVPMW=29,000, PVPMW=40,000, and PVPMW=1,300,000 are compared in ...

191. Agglomerated carbon nanotube-induced growth of piezoelectric 3D nanoarchitectures assembled from hollow 1D nanowires of poly (vinylidene fluoride) at high pressure.
Carbon nanotubes (CNTs) intrinsically tend to bundle and/or aggregate, and various techniques were explored to improve the dispersibility of CNTs in polymer matrices during the preparation of a variety of CNT/polymer based composites. However, herein we report the entangling nature of CNTs can be utilized for the rapid formation of unique piezoelectric three dimensional (3D) nanoarchitectures of p...

Natural polyphenol- stabilised highly crosslinked UHMWPE with high mechanical properties and low wear for joint implants
Radiation crosslinked ultra high molecular weight polyethylene (UHMWPE) with high mechanical strength, wear resistance, and oxidative stability is critical for the long term performance and life span of the joint implants based on crosslinked UHMWPE. The use of polyphenols are potential alternatives for the stabilisation of highly crosslinked UHMWPE for joint arthroplasty.
